MakeMethods::Template::PackageVar(3p)

NAME
Class::MakeMethods::Template::PackageVar - Static methods with global variables

SYNOPSIS
  package MyObject;
  use Class::MakeMethods::Template::PackageVar (
    scalar          => [ 'foo' ]
  );

  package main;

  MyObject->foo('bar')
  print MyObject->foo();

  $MyObject::foo = 'bazillion';
  print MyObject->foo();

DESCRIPTION
These meta-methods provide access to package (class global) variables. These are essentially the same as the Static meta-methods, except that they use a global variable in the declaring package to store their values.

Common Parameters: The following parameters are defined for PackageVar meta-methods.

variable
    The name of the variable to store the value in. Defaults to the same name as the method.

  Standard Methods
The following methods from Generic should all be supported:

  scalar
  string
  string_index (?)
  number
  boolean
  bits (?)
  array (*)
  hash (*)
  tiedhash (?)
  hash_of_arrays (?)
  object (?)
  instance (?)
  array_of_objects (?)
  code (?)
  code_or_scalar (?)

See Class::MakeMethods::Template::Generic for the interfaces and behaviors of these method types.

The items marked with a * above are specifically defined in this package, whereas the others are formed automatically by the interaction of this package's generic settings with the code templates provided by the Generic superclass.

The items marked with a ? above have not been tested sufficiently; please inform the author if they do not function as you would expect.

  PackageVar:vars
This rewrite rule converts package variable names into PackageVar methods of the equivalent data type.

Here's an example declaration:

  package MyClass;

  use Class::MakeMethods::Template::PackageVar (
    vars => '$DEBUG %Index'
  );

MyClass now has methods that get and set the contents of its $MyClass::DEBUG and %MyClass::Index package variables:

  MyClass->DEBUG( 1 );
  MyClass->Index( 'foo' => 'bar' );
